Template Files
Template files are reusable PHP files that define the structure and layout of a web page, allowing you to insert dynamic content into predefined locations.
When building web applications, it is useful to separate page layout from page content. Templates define the shared structure like headers, navigation, and footers, and leave space for dynamic content.
This keeps the layout consistent across all pages and allows you to update the design in one place instead of changing every file.
index.php
template.php
12345<?php // Main entry point $title = "Welcome"; $content = "<p>This is the home page content.</p>"; include 'template.php';
In this setup, the template.php file contains the HTML structure and uses placeholders for the $title and $content variables. The controller or view script, such as index.php, sets these variables and includes the template. This way, you inject dynamic content into the template without duplicating layout code.
index.php
template.php
1234567<?php $title = "About Us"; $sections = [ 'main' => "<p>About our company...</p>", 'sidebar' => "<ul><li>Contact</li><li>Team</li></ul>" ]; include 'template.php';
By supporting multiple content sections, your template system can handle more complex layouts. Each view or controller can set content for different areas, like a sidebar or main section, before including the template file. This approach makes it easy to reuse layouts for many pages while customizing the content for each one. Templates help keep your application consistent, as all pages share the same structure and style, reducing duplication and maintenance effort.
